Benefits of technology

The sensor unit described in this patent is designed to be attached to a housing from the other side in a simple way. This is possible because the sensor is positioned in a way that allows it to fit into the housing's accommodation hole. In this way, the sensor can be securely attached to the housing using a fixable part on the sensor and a vibration damper. The vibration damper helps absorb vibrations generated by the vibration generator, which can affect the sensor. Overall, this design simplifies the attachment process and reduces the impact of vibrations on the sensor's performance.

Problems solved by technology

The abutment of the touch sensor on the elastic member makes it difficult to attenuate a vibration of the touch sensor.

Abstract

A sensor unit attachable to a hole of a housing, closed by an overlay on one side in the first direction, from the other side in the first direction. The sensor unit includes a body, a sensor, a vibration generator, a vibration damper, and a fixable part. The body includes a first portion and a second portion on the other side in the first direction relative to the first portion. The sensor provided at the body detects a contact of a detection target with the overlay. The vibration generator can vibrate the body and sensor. The fixable part is provided at the second portion of the body. With the first portion accommodated in the hole, the fixable part is fixed to the housing from the other side in the first direction via the vibration damper, and the vibration damper is at least partly interposed between the fixable part and housing.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application claims priority under 35 U.S.C. § 119 of Japanese Patent Application No. 2020-078619 filed on Apr. 27, 2020, the disclosure of which is expressly incorporated by reference herein in its entirety.BACKGROUND OF THE INVENTIONTechnical Field[0002]The invention relates to sensor units and structures for attaching the sensor units.Background Art[0003]Japanese Unexamined Patent Application Publication No. 2012-173896 (hereinafter referred to as “literature”) describes a conventional structure for attaching a sensor unit. This structure includes a housing having a square ring shape, an elastic member having a square ring shape, and a sensor unit. The housing includes an accommodation hole, a pair of edges, and a pair of supports. The accommodation hole extends through the housing. The edges are opposite edges of the accommodation hole of the housing and have respective inner faces on a side of the accommodation hole. The s...
